[DeTomaso] Wilwood Brakes WTF????

[richard bosch]

Disc brakes require 2 psi residual pressure valves.Drum brakes have 10 psi. valves.
Most master cylinders have them under the flare seat  where the brake lines are screwed in thats why you do not normally see them or think about them.
Without the residual pressure the pistons retract much further in the caliper and there is a delay while the piston has to travel further before it contacts the rotor.Not good as seconds count in braking distance!
Mike's valves are "add ons" because his master cylinder does not have any valves built in.His valve pressure is correct as the pads did not drag on the rotors before the pad wear/cocked pad happened.
Just what i have learned from playing with lots of cars  :  )
